Heat pump Position ID Quantity Name

1 227758 6 Air|Water heat pump WPL 23 E

Air | water heat pump with enhanced vapour injection for heating and cooling. Can be used

as an outdoor or indoor installation version with corresponding accessories. The metal casing

is corrosion-protected and made from galvanised and powder-coated sheet steel with a stove

enamel finish. The refrigerant circuit is hermetically sealed, tested for leaks at the factory and

filled with safety refrigerant R407C. Twin flexible coupling for the compressor for reduced

sound power level. Thanks to enhanced vapour injection the scroll compressor is cooled at

low outside temperatures and a higher heating output is achieved. The wide fin spacing of the

evaporator enables low air resistance for noise reduction and improved defrosting. The 4/2-

way valve enables defrosting by reversing the circuit and the changeover of the refrigerant

circuit from heating to cooling mode. Biflow-capable electronic expansion valve with a

separate control unit and switching via the internal heat pump control unit (IWS) for

optimised overheating protection and therefore a higher COP. Time optimised and energy

steel, for combination with the WTS 30 E or WTS 40 E charging station as an accessory for

DHW heating. Cylinder for type SBB 751/1001 SOL with smooth tube internal coil to link up a

solar thermal system. The thermal insulation WDH SBB as an accessory ensures the lowest

heat losses. Protective anode as standard. Top and bottom flanged apertures are sealed with

a blank flange and can be equipped optionally with a flanged immersion heater (type FCR

28).8 231924 10 Thermal insulation WDH 1001 SBB

floorstanding DHW cylinders SBB 751/1001 and SBB 751/1001 SOL. Graphite inserts in the

EPTS and fleece for lowest heat losses. Wedge-shaped cut-outs and fleece layer ensure an

optimum match to the cylinder. Prepared adhesive joint in the wedge-shaped cut-outs

enables adjustment to the shape prior to installation. External plastic jacket in white; cover in

basalt grey. Thermal insulation secured with a quick-release hook strip.

10 230017 25 Solar flat-plate collector SOL 27 premium W

The collector is available for vertical and horizontal installation and thus designed specifically

for the relevant application. The laser-welded aluminium full area absorber with copper harp

is provided with highly selective vacuum coating (Miro-Therm). The hydraulic connection

between collectors is made by means of a plug-in connector system. An anti-reflection safety

glass cover protects the absorber and guarantees a high level of transmission. The collector is

insulated on the sides and back panel with low outgassing mineral wool (black backed). Its

main characteristic is low thermal conductivity. The hydraulic connection between collectors is

made by means of a plug-in connection system. Operating the collectors with a prepared

water:glycol mixture (H-30 L) provides the essential frost protection. The collector casing is

made from seawater-resistant aluminium.

11 230920 25 Mounting frame SOL R1 W

In combination with the fixing sets, the mounting frames SOL R1 and SOL R2 enable on-end

installation of the collectors next to each other. The SOL R1 W is specifically designed for

across installation of the collectors next to and above each other.

12 230171 20 Frame connection set SOL RV

The frame connection sets ensure secure connection of two mounting frames. The frame

connection set SOL RV should be used for connection in the case of on-end installation and

across installation next to each other. For across installation above each other, RV-W should

be selected.

13 230178 50 Mounting kit flat roof SOL BF-W

The SOL BF-W mounting kit allows horizontal installation of collectors on flat roofs or on the

wall.

14 230185 20 Push-fit connection SOL SV-A

The SOL SV-A plug-in connection provides the hydraulic connection of two rooftop collectors The SOL SV-A plug-in connection provides the hydraulic connection of two rooftop collectors

mounted one above the other.

15 230913 5 Push-fit connection SOL SV-F

The SOL SV-F push-fit connection is primarily intended for hydraulic connection of rooftop

collectors in the case of flat roof installation and wall mounting.

16 230141 1 Solar control unit SOM 6 plus

The solar control unit SOM 6 plus is used with standard solar heating systems. The

temperature differential control unit is designed for a single consumer. The standard setup is

programmed into the controller. A simple and intuitive menu guide is provided in the form of

pictorial graphics on the multi-function combination display. The display is backlit. Including 2

temperature sensor PT 1000, spare fuse, screws and rawl plugs, 4 strain reliefs and heat

conducting paste. Order the collector sensors separately.

17 165818 1 Temperature sensor PT 1000

lead material silicone, lead lengths 1450 mm, operating temperature -50 to +180 °C.

18 074100 25 Heat transfer liquid H30-LS, 20 l

Ready to use heat transfer medium (on polypropylene glycol basis) for solar systems with

corrosion and anti-boiling protection. Frost protection down to -30° (H-30 L) or -28° (H-30

LS).Never dilute with water. No health risks.

19 231899 2 Solar expansion vessel 80 l
